Izumi, a boy who was 7 years old, had recently relocated to a different city. Despite hearing numerous tales about the city's abundance of frightening vampires, he remained unconvinced. In his eyes, they appeared only as spooky stories to frighten and scare children.

Nevertheless, upon Izumi's arrival at his new school, he couldn't help but notice something peculiar: a student who consistently stayed in the shadows, steering clear of others. Izumi was intrigued by the enigmatic child who rarely spoke and did not engage with anyone. Eager and curious about meeting a new friend, Izumi made a plan to approach the quiet, mysterious kid in the near future.

However, what Izumi was unaware of was that the child he was very excited to get to know was not an average classmate—he was a vampire. Despite his paleness and eerie gaze, the vampire child concealed his true identity by staying hidden, preferring not to attract attention.

When Izumi got closer, his pure curiosity would lead him toward a surprising meeting, causing him to doubt all he believed about the city and its enigmatic residents.
